Hi my name is***** will be glad to help. Check the pulleys and belts for glaze, wear, rough or loose bearings , etc. Check the turbo and turbo piping for damage or leaks. Let me know
Thanks for the update... It would not be the fan hub or pulleys if they arent turning. Pressure test the charge air cooler and the intake piping. use a soapy water solution to check for bubbles indicating leaks. Remove the intake boot from the turbo and spin it by hand to see if it is contacting the housing at all. Let me know Check the clutch and throwout bearing and try greasing it to see if the noise may be in that area as well. Let me know
Hi Did you get this resolved?
